摘要:国家雪车雪橇中心是空间扭曲的异形赛道,对赛道内曲面平滑度的施工质量要求极高。利用BIM技术对地形逆向建模、空间异形赛道参数化建模、赛道模型深化应用及赛道内曲面成型检测等关键内容进行研究,可为同类型工程的施工和检测提供参考。首先,整合原始地貌模型和设计地形模型进行分析,计算出土方挖填工程量,有利于减少土方开挖和环境破坏;其次,采用Rhino软件拾取关键数据并进行纠偏处理,对异形赛道的夹具、钢筋、表面进行参数化建模及优化,解决赛道夹具安装定位与内曲面平整度控制的难题;最后,采用三维激光扫描技术对赛道内曲面平滑度进行动态控制,保证工程建造品质。
Abstract: The twisted anomalous track in the National Sliding Center is of extremely high construction quality for its track surface smoothness. BIM technology was used to study the key contents including reverse terrain modeling, parametric modeling of space shaped track, further application of track model, and surface forming inspection inside the track, which can provide reference for the construction and inspection of the similar projects later. Firstly, the earthwork excavation and filling engineering amount was calculated by integrating the original landform model and the designed terrain model for analysis, which was beneficial to reduce earthwork excavation. Secondly, Rhino software was used to pick up the key data and correct the deviation, then parametric models of the fixture, steel bar, and surface of the track were created and optimized to solve the problem of track fixture installation positioning and internal surface flatness control. Finally, the three-dimensional laser scanning technology was used to dynamically control the track surface smoothness, which effectively guaranteed the construction quality of the project.
